enum UT_ScaleInheritanceMode

strong

Scale inheritance modes.

Enumerator
DEFAULT	simple inheritance: W = L * pW
OFFSET_ONLY	child doesn't scale with the parent local scales, but local translation is scaled: W = SR * pLS^-1 * T * pW (Maya segment scale compensation)
OFFSET_AND_SCALE	local translation is scaled as before but parent local scaling is also reapplied by the child in local space: W = pLS * SR * pLS^-1 * T * pW (Softimage hierarchical scaling)
SCALE_ONLY	local translation is not scaled, but parent local scaling is reapplied by the child in local space: W = pLS * SRT * pLS^-1 * pW
IGNORE_PARENT_LOCAL	child completely ignores any parent local scaling: W = SRT * pLS^-1 * pW
